Your residence is your permanent home:
- This is the dwelling you use as a home whether you own it or if you may someday leave.
- It is a place where you remain when you are not elsewhere for work or other temporary purposes.
- You don’t change residency when you are away from home for a prolonged period.
- You only change residency when you leave your home and don’t intend to return, but instead, establish a new home elsewhere.
